Best Cheap NAS of the Year

Cheap NAS hardware in 2025 sits in an awkward middle ground between full DIY servers and polished, premium turnkey appliances, but it is also where many first time buyers start when they want to get away from cloud storage and subscriptions without spending a large amount of money. This article focuses on systems that have been available for under $249, arrive pre built with CPU and memory, and come either with their own NAS style operating system or with enough onboard storage to install one easily. The aim is to show what you realistically get at this price in terms of bays, network speed, scale and software, and where each device draws the line on features, expansion and flexibility so you can decide whether a low cost 2 bay box, an all M.2 cube or a bare board server is the better fit for your first step into local storage.


#1 UGREEN NASync DH2300 – $178 to $209

SPECS: Rockchip RK3576 8 core ARM up to 2.2 GHz – 4 GB LPDDR4X – 2 x 3.5″/2.5″ SATA bays (up to 60 TB total) – 1 x 1 GbE RJ45 – no internal M.2 SSD slots, 32 GB eMMC OS storage.

The UGREEN NASync DH2300 is aimed at users who want the cheapest possible entry to a proper NAS without losing basic RAID and a guided setup experience. Two SATA bays and support for up to 60 TB in RAID 0, RAID 1, JBOD or Basic give enough room for a modest media library, photo archive and PC backups, while UGOS Pro adds mobile apps, 4K HDMI playback, simple remote access and basic snapshot and multi user features in a consumer friendly interface. Power draw is low, thanks to the 8 core ARM SoC and 1 GbE networking, which also keeps noise and heat down compared with larger multi bay units. The key limitation at this price is that you are locked to 2 drive bays, a single 1 GbE port and no internal SSD caching or containers on this model, so long term scale and heavy app use are constrained. Overall it suits buyers who want a cheap, mostly turnkey alternative to cloud storage and USB drives, rather than a platform for heavier virtualization or high speed workloads.

What we said in our October 2025 Review HERE:

The UGREEN DH2300 represents a carefully positioned step in the company’s ongoing effort to make private storage approachable for non-technical users. Its hardware configuration, led by the Rockchip RK3576 processor and 4GB of fixed memory, provides solid baseline performance for a two-bay ARM-powered NAS at this price point. Although its single 1GbE network port may limit throughput for larger file transfers, the system compensates with a highly efficient power profile, quiet operation, and full support for common RAID configurations. The inclusion of a dedicated 32GB eMMC system drive, HDMI 4K60 output, and an NPU capable of AI-based photo indexing places it above most similarly priced entry-level alternatives from QNAP and Synology. However, certain aspects of UGREEN’s marketing—particularly the way the dual quad-core CPU clusters are presented as a single 8-core design—could be clearer. Likewise, the absence of upgradeable memory or faster networking options limits its long-term scalability for users seeking to expand their NAS environment beyond basic media and backup tasks.

From a broader standpoint, the DH2300’s strongest appeal lies in its simplicity and low operational overhead. UGOS Pro, though still developing in maturity, has evolved into a competent, user-friendly platform offering the key features needed for home data management, multimedia access, and scheduled backups. The OS’s stability, combined with efficient hardware and lightweight design, makes this NAS a practical alternative to annual cloud subscriptions for users who simply want local control over their data. It is not a system aimed at enthusiasts or professionals demanding virtual machines, multi-gig networking, or broad third-party OS support, but rather those seeking a self-contained, reliable, and low-maintenance device. Within that niche, the DH2300 delivers strong value and performs consistently well for the intended demographic—serving as an accessible first step into local storage ownership.

#2 UniFi UNAS 2 – $199

SPECS: Quad core ARM Cortex A55 1.7 GHz – 4 GB RAM – 2 x 3.5″/2.5″ SATA bays – 1 x 2.5 GbE RJ45 with PoE++ – no internal M.2 SSD slots, 1 x USB C 5 Gb/s expansion.

UniFi UNAS 2 targets users already invested in the UniFi ecosystem who want basic network storage and UniFi Drive integration at a low buy in price. Two SATA bays are enough for a mirrored pair of HDDs or SSDs for small site backups, UniFi Protect recordings or general file storage, and the 2.5 GbE plus PoE++ design keeps cabling simple by combining power and data on a single link to an existing UniFi switch. UniFi OS and UniFi Drive provide a simplified management layer for object storage, simple file shares and cloud synced folders, with a small color LCM display giving at a glance system status without needing to log in. The main limitation at this price is that UniFi’s NAS software is still relatively immature, with no native support for third party media servers or advanced NAS apps and no SSD cache tier, so it is best treated as a small, integrated storage node rather than a full featured general purpose NAS. For users who want a cheap box that drops straight into a UniFi rack and handles basic storage quietly and efficiently, it fits that role.

What we said in our September 2025 Review HERE:

The UniFi UNAS 2 is presented as a compact and affordable two-bay NAS designed for straightforward storage and backup tasks, particularly within environments already using UniFi networking hardware. Its PoE++ design is distinctive, allowing both power and connectivity to be delivered over a single cable, simplifying installation where compatible PoE switches are available. This approach aligns with UniFi’s strategy of reducing external hardware requirements, though it also means that a failed port or damaged cable will disable both power and network access simultaneously. For non-UniFi users, the reliance on PoE++ creates an additional barrier, as adoption requires either compatible infrastructure or the included 60W injector. The shared dual-drive tray, lack of hot-swap support, and absence of expansion options further reinforce the system’s role as a fixed-capacity solution, best suited to smaller or secondary deployments. With a maximum drive budget of 52W and overall consumption limited to 60W, the device is power-efficient, but its architecture prioritises simplicity over flexibility.

On the software side, the UNAS 2 provides a user-friendly interface with access to snapshots, RAID configuration, system backups, and integration into the UniFi identity ecosystem. However, the limited hardware constrains the range of features available, and certain tools seen in UniFi’s larger NAS models are absent, such as encrypted volumes or extended network protocol support. Performance testing showed sequential read speeds up to 260 MB/s and write speeds around 160–180 MB/s, which make full use of the 2.5 GbE interface but leave little headroom for more demanding tasks. Thermals during extended use regularly pushed the CPU into the high 70s Celsius, and although fan management can be adjusted, sustained workloads highlight the limits of the system’s cooling design. The software’s omission of iSCSI and advanced backup filters also narrows its role, making it less competitive against established vendors in professional or virtualisation scenarios.

Ultimately, the UNAS 2 is most appropriately positioned as an edge or secondary NAS, providing basic networked storage for existing UniFi users who value plug-and-play deployment and ecosystem consistency, but it is not equipped to serve as a primary system in larger or more demanding environments (VMs, Containers, etc). A great and unique NAS that will nbe at it’s most appealing if you are already invested in the UniFi ecosystem, or have a NAS already that needs a network backup.

#3 Beelink ME Mini – $209 to $279

SPECS: Intel Processor N150 quad core up to 3.6 GHz – 12 GB or 16 GB LPDDR5 – 0 x SATA bays / 6 x M.2 2280 NVMe slots (5 x PCIe 3.0 x1, 1 x PCIe 3.0 x2, up to 24 TB) – 2 x 2.5 GbE RJ45 – 64 GB eMMC plus up to 2 TB NVMe preinstalled.

The Beelink ME Mini trades spinning disks for six M.2 slots in a 99 mm cube, making it one of the most storage dense budget options for users who already have or plan to buy multiple NVMe SSDs. At this price bracket it offers far more raw flash capacity potential than traditional 2 bay HDD NAS units, and the dual 2.5 GbE ports allow the box to push enough throughput for small media servers, backup targets and home lab services once an appropriate OS such as TrueNAS, Proxmox, Linux or a lightweight NAS distribution is installed. The integrated PSU, WiFi 6 and compact chimney style cooling keep the physical footprint small while still supporting continuous operation as a low to moderate power SSD based server. The main limitation is that PCIe lane allocation and the N150 CPU cap per drive performance and the unit can run hot under sustained load, so you do not get high end NVMe speeds from each slot and there is no turnkey NAS OS included. It is therefore best suited to buyers who value maximum flash capacity per dollar in a very small chassis and are comfortable treating it as a DIY NAS platform rather than a plug-and-play appliance.

What we said in our June ’25 Review HERE:

The Beelink ME Mini NAS delivers an uncommon blend of size, functionality, and efficiency in a market segment often dominated by larger, louder, and less integrated alternatives. It is not designed to compete with traditional enterprise-grade NAS devices or modular, scalable solutions for prosumers. Instead, its strengths lie in targeting the needs of home users who want a quiet, energy-efficient storage solution that is easy to deploy, aesthetically unobtrusive, and capable of handling daily tasks such as media streaming, file backup, or soft routing. The inclusion of six M.2 NVMe SSD slots—paired with a Gen 3 x2 system slot—offers a rare level of expansion in such a small enclosure. The integration of an internal PSU, silent fan-assisted cooling, and a surprisingly effective thermal design are thoughtful touches that differentiate it from the majority of DIY NAS mini PCs.

That said, it is not without limitations. The memory is non-upgradable, thermal accumulation at the base suggests room for improvement, and bandwidth ceilings imposed by Gen 3 x1 lanes will constrain users who demand high parallel throughput. Still, for its price point—particularly when pre-order discounts are applied—the ME Mini offers significant value, especially when compared to ARM-based NAS solutions with similar or lower specifications. With bundled Crucial SSD options and support for a wide range of NAS operating systems, it positions itself as a ready-to-go platform for tech-savvy users wanting to avoid the assembly of a fully DIY system. Overall, while not a product for every use case, the Beelink ME Mini succeeds in its aim to be a compact, stylish, and capable home NAS.

#4 Xyber Hydra N150 – around $208 to $249

SPECS: Intel Processor N150 quad core up to 3.6 GHz – 16 GB LPDDR5 – 0 x SATA bays / 4 x M.2 2280 NVMe PCIe 3.0 x2 slots – 2 x 2.5 GbE RJ45 plus WiFi 6 – 64 GB eMMC with Ubuntu preinstalled and 512 GB NVMe SSD included on many models.

The Xyber Hydra N150 aims at budget buyers who want an NVMe based NAS that is closer to ready out of the box, combining 4 PCIe 3.0 x2 M.2 bays with 16 GB of memory, preloaded Ubuntu and often a preinstalled 512 GB NVMe system drive. That combination makes it straightforward to stand up containers, Docker stacks or lightweight NAS services immediately, then expand capacity by populating the remaining M.2 slots with SSDs as budget allows. Dual 2.5 GbE ports with link aggregation give enough network bandwidth to take advantage of parallel NVMe arrays for home lab or small office workloads, and the revised metal baseplate plus dual fan cooling run cooler than earlier G9 derived designs while still keeping power use modest. The main limitation at this price is that RAM is soldered and each M.2 slot is only x2, so neither memory capacity nor per drive bandwidth can be increased later, and some tuning of fan curves is needed to keep thermals in check under heavy use. For users who want an inexpensive, compact NVMe appliance with more polish than bare boards but are comfortable managing their own OS and RAID layout, it offers a pragmatic middle ground.

What we said in our July ’25 Review HERE:

The Xyber Hydra N150 NAS represents a deliberate and measured evolution of the budget-friendly compact NAS formula, clearly designed to resolve key weaknesses of similar products like the GMKTec G9 without altering the fundamental architecture. Its use of a thicker, thermally conductive metal base plate provides demonstrable improvement in heat dissipation compared to the plastic underside of the G9, a difference borne out in extended load testing where temperatures stabilized more quickly and stayed lower when fan profiles were adjusted. The pre-installed 64GB eMMC module running Ubuntu out of the box eliminates the initial configuration barrier often faced by novice users, while still allowing more experienced users to easily replace it with their OS of choice, such as ZimaOS or TrueNAS. The inclusion of a 512GB NVMe SSD in the primary M.2 bay adds immediate storage capacity without requiring an upfront investment in additional drives, an uncommon but practical feature at this price point.

Internally, the decision to provide 16GB of fixed LPDDR5 memory — 4GB more than its nearest comparable competitor — gives the Hydra slightly more headroom for memory-intensive tasks, such as running lightweight container workloads or maintaining a larger metadata cache for media streaming applications. While the memory remains non-upgradable, the choice of capacity is a reasonable compromise given the constraints of the Intel N150 platform and the system’s focus on cost efficiency. The integrated Wi-Fi 6 module, with dual antennas and full UnRAID compatibility, is another meaningful addition, enabling wireless deployments where cabling is impractical and expanding the deployment scenarios for home and small office users. These subtle but important upgrades make the Hydra feel more complete out of the box, catering to a broader range of use cases with fewer compromises.

That said, the Hydra still shares many of the inherent trade-offs of its class. The N150 processor is adequate for modest workloads, but becomes saturated under sustained high parallel usage, especially when all four M.2 slots are simultaneously active and the CPU nears 100% utilization. The PCIe lane limitations of the platform, with each M.2 slot limited to Gen3 x2 speeds, restrict the aggregate performance potential of RAID arrays or concurrent high-bandwidth operations. Similarly, the continued reliance on dual 2.5GbE ports limits maximum external throughput despite the internal SSD bandwidth being capable of more, and although M.2-to-10GbE adapters remain an option, they come at the cost of sacrificing one storage slot. BIOS-level adjustments are also required to extract the best thermal and fan performance under heavy use, something that more advanced users will appreciate but could frustrate beginners.

Overall, at its introductory price of $218.99, the Xyber Hydra N150 achieves a strong balance of value, practicality, and refinement in the entry-level NAS segment. The thoughtful inclusion of extras — the 64GB bootable eMMC, 512GB SSD, improved cooling, and additional memory — make it feel more turnkey than competing models, while still leaving room for advanced customization. It’s a sensible option for users seeking a compact and efficient NAS for personal cloud storage, light virtualization, or as a dedicated media server, provided expectations around CPU and networking throughput are kept realistic. For its target audience, the Hydra is a compelling and notably improved choice that addresses many of the criticisms of earlier designs without abandoning the affordability that defines this class of devices.

#5 ZimaBoard 2 1664 – $239 to $349

SPECS: Intel Processor N150 quad core up to 3.6 GHz – 16 GB LPDDR5X – 2 x SATA 3.0 ports (via cables to external drives) – 2 x 2.5 GbE RJ45 – 1 x PCIe 3.0 x4 slot, 64 GB eMMC OS storage.

ZimaBoard 2 1664 is a single board x86 server positioned for budget home lab builders who want more flexibility than a fixed enclosure can offer while staying under typical entry level NAS pricing. The board exposes 2 SATA ports with power for attaching HDDs or SSDs in whatever chassis or external mounting the user prefers, alongside dual 2.5 GbE, USB 3, Mini DisplayPort and a full PCIe 3.0 x4 slot that can host extra NICs, HBAs or NVMe adaptors to scale storage and connectivity over time. ZimaOS comes preinstalled and supports alternative systems such as CasaOS, Linux and Windows, so it can act as a low cost base for self hosted services, small virtualisation labs or custom NAS builds using external drive cages or repurposed cases. The main limitation is that there is no built in drive bay system or enclosure, so buyers must factor in the cost and effort of adding their own storage chassis, cabling and cooling if they want something as neat as a traditional NAS. For those willing to do that, it offers one of the most flexible and expandable x86 platforms in the budget bracket, with enough CPU and RAM headroom to grow beyond simple file serving as needs evolve.

What we said in our April ’25 Review HERE:

The ZimaBoard 2 is a competent and thoughtfully assembled single-board server that builds meaningfully on IceWhale’s earlier efforts, especially the original ZimaBoard and the ZimaBlade. Its design clearly targets users who want more flexibility and performance than traditional ARM-based boards can offer, but who also value power efficiency, silence, and a small footprint. The use of an Intel N150 CPU, 8GB of LPDDR5x memory, dual 2.5GbE ports, and a PCIe 3.0 x4 slot makes it viable for a variety of home server roles—from basic NAS and smart home coordination to lightweight container hosting and local media streaming. Features like onboard SATA, USB 3.1, and a DisplayPort connection further add to its utility. However, there are hardware limitations that may affect long-term suitability for advanced deployments. The soldered RAM cannot be upgraded, and the internal eMMC storage, while useful for initial setup, is too slow for OS-level responsiveness in more demanding use cases. Passive cooling, while appreciated for silence, also imposes some thermal limitations depending on the deployment environment.

On the software side, ZimaOS offers a decent out-of-the-box experience that caters to users with minimal technical background. It handles core tasks like application deployment, file sharing, and system monitoring without requiring advanced configuration, and its Docker-based App Store simplifies access to popular tools. For more experienced users, the system supports third-party OS installation, which is likely how many will ultimately use the ZimaBoard 2. Still, as a bundled solution, ZimaOS has matured significantly and now presents itself as a lightweight, capable, and non-intrusive platform for those who prefer to get started immediately. In the broader context of DIY server hardware, ZimaBoard 2 occupies a middle ground: more powerful and modular than Raspberry Pi-class systems, yet more constrained than full x86 mini PCs or enthusiast-grade NAS hardware. For those who understand and accept these trade-offs, and are willing to plan around its limitations, the ZimaBoard 2 offers a reliable and flexible foundation for compact, energy-efficient computing at the edge.

Taken together, the UGREEN DH2300, UniFi UNAS 2, Beelink ME Mini, Xyber Hydra N150 and ZimaBoard 2 show the different ways vendors are trying to hit the sub 250 dollar bracket without stripping out the core value of a NAS. Some focus on simplicity and bundled software with limited scale, others trade turnkey polish for dense NVMe storage or flexible bare board layouts that assume you are willing to do more of the setup yourself. None of these devices removes the usual compromises around bays, performance, noise or software maturity at this price level, but each offers a clear path away from pure cloud dependence and USB drives. The practical decision is less about which is objectively “best” and more about whether you want a small 2 bay appliance, a compact all flash cube or a configurable single board system that can grow with your skills and requirements over time.

UGREEN DH4300 vs DXP4800 PLUS NAS Comparison

Par : Rob Andrews
6 octobre 2025 à 16:00

UGREEN DXP4800 PLUS vs DH4300 NAS – Which Should You Buy?

UGREEN’s emergence into the NAS market has been notably rapid, expanding from its early DXP series Kickstarter campaigns in 2024 to a full retail presence in 2025. Among its growing portfolio, two models now define the entry and mid-range segments of the company’s lineup: the DH4300 Plus and the DXP4800 Plus. Both are 4-bay NAS systems built around UGREEN’s in-house UGOS Pro operating system, offering cross-platform client access, RAID options, and remote synchronization. However, beneath their similar exteriors lie significant differences in design philosophy, hardware architecture, and expandability. The DH4300 represents the brand’s low-power ARM-based solution focused on simplicity and efficiency, while the DXP4800 Plus adopts an Intel x86 platform that aims to deliver higher throughput, broader software compatibility, and long-term scalability. This comparison examines each system in detail to identify where their strengths diverge and which one may better align with different user priorities.

DH4300 vs DXP4800 PLUS – Design and Storage

Both the DH4300 Plus and DXP4800 Plus are 4-bay NAS systems, yet their physical execution and approach to storage differ substantially. The DH4300 Plus adopts a compact vertical cube form, measuring just 155mm per side, prioritizing low noise and minimal desk footprint. It uses plastic top-loading trays that can house either 2.5-inch SSDs or 3.5-inch HDDs. Drives are inserted vertically from the top, secured internally via SATA connectors. This layout helps keep the system small and easy to position in tighter setups but limits front-access servicing and restricts the unit’s suitability for hot-swap drive replacement. The DXP4800 Plus, by contrast, uses a more conventional front-loading 4-bay metal chassis that resembles traditional NAS systems from Synology or QNAP. Each tray includes a locking mechanism, supports hot-swapping, and accepts both 3.5-inch and 2.5-inch media. The metal body contributes to improved heat dissipation and rigidity, though it also results in higher weight and slightly higher fan noise. The chassis design clearly targets users expecting long-term durability and easier drive maintenance.

Beyond the drive trays themselves, the DXP4800 Plus expands the internal storage configuration by adding two M.2 NVMe slots. These can be assigned for SSD caching or as additional high-speed storage pools. This flexibility is absent in the DH4300 Plus, which is limited to its four SATA bays. The M.2 capability allows the DXP4800 Plus to create tiered storage setups that combine large-capacity HDDs with SSD acceleration, a feature relevant to media libraries or multi-user data environments requiring rapid retrieval. A key architectural distinction lies in their system drives. The DH4300 Plus relies on a 32GB eMMC flash module, while the DXP4800 Plus integrates a 128GB NVMe SSD dedicated to UGOS Pro. The SSD delivers faster system responsiveness, reduced latency, and provides enough capacity to install alternative operating systems if the user chooses. The eMMC module, while efficient, is considerably slower and less flexible for advanced tasks such as dual-boot environments or virtualized OS installations.

Both systems officially support up to 30TB drives per bay, giving the DH4300 Plus a theoretical ceiling of 120TB, while the DXP4800 Plus extends to 136TB when the NVMe bays are included. The practical implication is straightforward: the DXP4800 Plus provides more room to grow, both in capacity and performance scaling. For users seeking long-term expandability and tiered storage, the Intel-based unit presents the more adaptable platform. Meanwhile, those prioritizing compactness, lower power draw, and quiet operation may find the DH4300 Plus’ simplified vertical design sufficient for modest home or small-office workloads.

DXP4800 PLUS vs DH4300 – Internal Hardware

The UGREEN DH4300 Plus is powered by a Rockchip ARM processor built on a big.LITTLE configuration consisting of four Cortex-A76 and four Cortex-A55 cores, clocked at up to 2.0GHz. This eight-core design is efficient and well-suited for basic NAS tasks such as file sharing, backups, and light multimedia use. The processor is paired with 8GB of LPDDR4X memory that is soldered to the mainboard and non-upgradable. Power efficiency is a major strength of this configuration, typically consuming less than half the power of Intel-based systems when idle. However, its ARM architecture inherently restricts compatibility with x86 applications, virtual machines, and certain Docker containers, limiting its scope for heavier workloads.

By contrast, the DXP4800 Plus employs an Intel Pentium Gold 8505, a five-core, six-thread processor from Intel’s 12th Generation “Alder Lake” family. This hybrid x86 chip combines a single Performance core and four Efficient cores, supporting hardware virtualization, AVX2 instruction sets, and Intel UHD Graphics. Paired with 8GB of DDR5 memory, expandable up to 64GB, the DXP4800 Plus accommodates far more demanding tasks, including Docker deployments, Plex hardware transcoding, and multiple concurrent user operations. The use of DDR5 not only increases bandwidth but also introduces on-die error correction (ODECC) for improved data integrity, especially under sustained workloads.

Thermally, the two models are built with different cooling philosophies. The DH4300 Plus relies on its plastic housing and a single rear fan to quietly manage airflow, maintaining modest heat output even under continuous drive access. The DXP4800 Plus uses a metal chassis with enhanced thermal conduction and larger active cooling components to handle its higher power draw and CPU thermal output. As a result, it operates at a higher baseline wattage but sustains performance under extended heavy loads without throttling.

The difference between these platforms is clear: the DH4300 Plus targets efficiency and affordability, while the DXP4800 Plus prioritizes raw performance, expandability, and compatibility. The ARM-based model functions effectively as a quiet, low-cost personal cloud, whereas the Intel-powered alternative transitions closer to a professional or prosumer NAS capable of handling heavier workloads and future expansion.

DH4300 vs DXP4800 PLUS – Connectivity

The connectivity options on these two NAS systems reinforce their differing design priorities. The UGREEN DH4300 Plus offers a minimal, streamlined interface aimed at simplicity. It features a single 2.5GbE LAN port, sufficient for small network environments or home setups. This port provides adequate throughput for multi-user file access, media streaming, and backups, but limits scalability for link aggregation or 10GbE network integration. On the front, the DH4300 Plus includes one USB-C (5Gb/s) and two USB-A (5Gb/s) ports for connecting external storage or peripheral devices. Around the back, a 4K HDMI 2.0 output is provided, allowing direct media playback or access to the NAS desktop interface through a monitor and keyboard. Although compact and functional, the absence of additional network interfaces or expansion options means the DH4300 Plus is a closed system with limited upgrade flexibility.

The DXP4800 Plus presents a markedly broader I/O profile. Networking is handled by both a 2.5GbE and a 10GbE RJ45 port, enabling dual-network configurations, link aggregation, or high-speed connectivity to 10GbE switches and workstations. This combination provides a clear advantage for environments with large data transfers, such as video editing, virtualization, or backup synchronization across multiple systems. USB connectivity is also improved, with a front USB-C and USB-A port (each 10Gb/s), plus three additional rear USB-A ports—one at 5Gb/s and two at USB 2.0 speeds for legacy devices. The inclusion of an SD 3.0 card reader on the front panel enhances convenience for photographers or media professionals who regularly import content.

Both models offer HDMI output supporting 4K display, but only the DXP4800 Plus benefits from Intel’s integrated UHD Graphics, allowing smoother playback and better compatibility with third-party applications such as Plex, Jellyfin, or VLC in a connected display mode. The DH4300’s ARM GPU can output a graphical interface but struggles with higher bitrates and complex codec formats. Neither system includes PCIe or Thunderbolt expansion, although the DXP4800 Plus is more likely to support future USB-based expansion storage, given its higher USB bandwidth and processing headroom.

The result is a distinct separation in capability: the DH4300 Plus offers the essentials for simple network storage and direct access, while the DXP4800 Plus is engineered to serve as a central node in more advanced home or office networks, handling high-speed workflows and multi-interface operations with ease.

DH4300 vs DXP4800 PLUS – Software and Services

Both NAS systems operate on UGREEN’s UGOS Pro, the company’s in-house Linux-based operating system that has evolved considerably since its debut. UGOS Pro delivers a browser-accessible interface and companion apps for desktop and mobile devices, providing cross-platform file management, media streaming, and remote synchronization. Both the DH4300 Plus and DXP4800 Plus share the same core software experience, including snapshot protection, multi-tier backup utilities, RAID configuration tools, and cloud synchronization with popular platforms such as Google Drive, Dropbox, and OneDrive. Remote access can be achieved through relay services or secure connections such as Tailscale VPN, enabling users to maintain access without direct port forwarding.

Where the differences begin to emerge is in application scope and performance. The ARM-based DH4300 Plus supports a subset of the total UGOS Pro app library, running core services such as file sharing, photo management, and music/video playback, but it is limited when it comes to containerization and virtualization. Its CPU architecture prevents the use of virtual machines and restricts Docker to lightweight ARM-compatible containers. This makes it a suitable platform for personal data hosting or small-scale media libraries but less appropriate for professional or experimental use cases.

The DXP4800 Plus, leveraging its Intel x86 CPU and larger memory capacity, unlocks the full UGOS Pro ecosystem. It supports Docker for containerized applications and a dedicated Virtual Machine Manager, allowing users to run Windows, Ubuntu, or Android environments directly on the NAS. This hardware advantage extends to AI-based services integrated into UGOS Pro, including facial and object recognition within the Photo app. The DXP4800 Plus processes these functions locally at higher speed and with greater precision, while the DH4300 Plus delivers only basic recognition due to its lower AI compute capability.

Media handling is another clear differentiator. Both NAS units can run the native UGREEN Theater app for video playback, but the DXP4800 Plus benefits from hardware-accelerated 4K transcoding via Intel UHD Graphics. This enables smooth playback across Plex, Jellyfin, and Emby, even for HEVC or high-bitrate formats. The DH4300 Plus lacks equivalent hardware decoding support and therefore relies on software rendering, which can lead to stuttering or incompatibility when streaming demanding media.

Overall, UGOS Pro maintains functional parity across both systems at the surface level, yet the DXP4800 Plus unlocks a broader range of use cases—from virtualization to heavier AI and multimedia workloads. The DH4300 Plus remains best suited to users seeking a straightforward, reliable network storage environment without advanced compute or scalability expectations.

DXP4800 PLUS vs DH4300 – Verdict & Conclusion

The UGREEN DH4300 Plus and DXP4800 Plus ultimately cater to two very different categories of users, despite sharing the same UGOS Pro ecosystem and similar 4-bay configurations. The DH4300 Plus is built for simplicity, energy efficiency, and quiet continuous operation. Its ARM-based design consumes far less power and generates minimal heat, which is appealing for users who want a NAS that can run 24/7 in a home or office without significant energy cost or noise impact. It handles standard NAS duties—file storage, scheduled backups, photo management, and light multimedia playback—without issue. However, its hardware limitations restrict its suitability for more advanced workloads such as containerized apps, virtual machines, or high-resolution video transcoding. This makes the DH4300 Plus ideal for users seeking dependable, local network storage that functions as a personal cloud or central backup hub, not as an extensible compute platform.

The DXP4800 Plus, on the other hand, occupies a very different space in UGREEN’s product strategy. Its x86 Intel processor, DDR5 memory, dual-network connectivity (including 10GbE), and support for NVMe caching elevate it closer to what many would consider a professional-grade NAS system. It offers faster response times, wider compatibility with third-party applications, and a platform that supports future scalability through additional storage, memory, and software deployments. This system also opens the door to real virtualization, Docker-based workloads, and higher performance in media services thanks to Intel’s hardware-accelerated graphics. While it requires more power and a higher upfront investment, it delivers a measurable leap in flexibility, stability under heavier loads, and long-term performance headroom.

In practical terms, the DH4300 Plus will satisfy users who simply want to move away from cloud reliance, consolidate data locally, and maintain low running costs. The DXP4800 Plus suits those who expect their NAS to perform as both a data server and an active processing node for AI indexing, 4K media handling, or business-level file operations. Both systems are well-built, and UGOS Pro continues to mature into a stable operating environment, but the DXP4800 Plus clearly represents the more capable and future-ready choice. The DH4300 Plus fulfills its role as a compact, accessible entry into local network storage, while the DXP4800 Plus defines UGREEN’s current benchmark for serious, performance-oriented users.

Why the UGREEN US3000 UPS is Important/Interesting

Uninterruptible power supplies are not new, but most consumer models are designed for general computing and rely on bulky lead-acid batteries with AC pass-through. The UGREEN US3000 differs by offering a DC-to-DC solution that matches the external power design of UGREEN NAS units. This means it eliminates the inefficiency of double conversion and avoids the audible transfer delays that can occur with traditional UPS hardware. With a 120 W output ceiling, it is tailored for single-device use rather than multiple systems, but that specificity ensures closer integration with the NAS’s power and shutdown controls. From a technical perspective, its lithium-ion battery pack offers greater energy density than lead-acid, allowing the device to remain compact while still covering several minutes of safe system operation during an outage.

The importance of this UPS becomes clearer when examining how it interacts with UGOS Pro. Unlike generic solutions, the US3000 communicates directly with the NAS operating system via a USB connection, exposing monitoring and automation options in the control panel. Users can configure automatic shutdown after a set period, trigger standby to conserve remaining charge, or enable auto-restart once mains power returns. These features are not just convenient but directly address the risks of corrupted writes, incomplete backups, or damaged RAID arrays during sudden power loss. Given that UGREEN NAS systems are designed for small offices and home use, where environments may not include larger enterprise-grade UPS equipment, the US3000 effectively bridges that gap by offering a purpose-built, compact, and integrated safeguard.

UGREEN US3000 UPS Review – Design

The UGREEN US3000 follows a compact, rectangular form factor with dimensions of 120.6 mm in length, 80.5 mm in width, and 29.6 mm in thickness. Its weight of just under 440 g makes it relatively lightweight for a UPS, reflecting its focus on portability and single-device deployment rather than large-scale power protection. The outer chassis is made from anodized and sandblasted aluminum alloy, which gives it improved durability compared with plastic housings and also aids in passive heat dissipation. The choice of materials ensures a consistent finish that aligns visually with UGREEN’s NAS enclosures, providing an integrated appearance when the two devices are used together on a desktop.

Connectivity is handled entirely through DC and USB ports positioned on a single side of the device. The panel includes a DC input, a DC output, a USB-C port for data communication, and a power button. The fixed DC cable has a length of approximately 28 cm, while the included USB-A to USB-C cable measures around 53 cm, allowing flexible placement next to a NAS system without excess cabling. Each port and control is clearly labeled with printed icons, reducing the likelihood of incorrect setup. Unlike conventional UPS systems that feature multiple AC sockets, the US3000 focuses on a single dedicated output, reflecting its intended role as a companion unit for UGREEN NAS models rather than a general-purpose UPS.

The packaging of the device mirrors UGREEN’s approach with its NAS line, offering clear product imagery and specification highlights on the box exterior. Inside, the unit is provided with a base stand for stable positioning, the aforementioned data cable, and basic documentation. This is a minimalist package compared to conventional UPS units, which often include multiple adaptors or accessories, but the streamlined approach ensures that setup remains straightforward for the intended NAS integration. The inclusion of a stand is particularly useful given the slim design, as it helps keep the UPS stable in vertical placement while maintaining airflow around the chassis.

From a design perspective, the emphasis is on simplicity and integration rather than flexibility. The device does not feature multiple voltage outputs, nor does it support powering unrelated devices such as routers or switches. Instead, its DC pass-through design, small footprint, and single-device orientation mark it as a specialized tool. This aligns with UGREEN’s approach of building a controlled ecosystem around its NAS systems, where accessories are engineered for direct compatibility. The US3000 therefore sits between consumer-grade battery packs and enterprise UPS units, offering a focused solution that fits into a narrow but clearly defined usage scenario.

UGREEN US3000 UPS Review – Internal Power Design

Inside the UGREEN US3000 is a straightforward but carefully constructed layout built around a 12,000 mAh lithium-ion battery pack. The pack consists of four SunPower INR18650-3000 cells, each rated at 3000 mAh and 11.1 Wh, connected in series to deliver a combined rated energy of 43.2 Wh at 14.4 V. The cells are wrapped in foam insulation and secured with adhesive to minimize movement, with spot-welded nickel strips linking them. Additional barley paper insulation is applied around the terminals for added protection. This design choice allows the UPS to maintain compact dimensions while ensuring sufficient runtime for controlled NAS shutdowns.

Battery management is handled by a Chipsea CBM8580KV6NT protection IC. This chip monitors voltage, current, and temperature across the pack, ensuring safe charging and discharge cycles. It communicates with the system host via SMBus 3.1, which enables the UPS to relay real-time status to the NAS when connected through USB. Supporting components include current sense resistors, thermistors, and MOSFETs for switching and power regulation. Together, these ensure not only that the battery operates safely but also that the UPS can reliably deliver 120 W maximum output without voltage instability.

Voltage conversion is performed by a dual-stage arrangement. A Texas Instruments TPS55289 synchronous buck-boost converter handles a wide input range up to 30 V and can output between 0.8 V and 22 V. Alongside this, a SouthChip SC8002 synchronous buck controller manages current limiting and efficiency across dual channels. Power MOSFETs from CR MICRO and NCEPower are used for pass-through control and output switching, while a GigaDevice GD32F303RCT6 Cortex-M4 microcontroller coordinates the overall system, including communication with the NAS. Passive cooling, adhesive reinforcement on inductors and capacitors, and fuses at both input and battery ends further underline the design focus on stability and safety.

UGREEN US3000 UPS Review – Testing with UGREEN NASync Systems

To evaluate the UGREEN US3000, three operational scenarios were simulated: immediate power loss with continued operation, automatic shutdown under UPS control, and timed shutdown with automatic restart when power returned. In each case, the NAS was connected to the UPS using both the DC input and USB communication cable to ensure full integration with UGOS Pro. The first test involved disconnecting mains power to replicate an outage. The NAS continued running without interruption, with the transfer to battery occurring instantly. System logs registered the event in under two seconds, and normal file access, media playback, and downloads remained available until the battery level dropped to the configured threshold.

In the second test, the system was configured to shut down automatically as soon as the UPS switched to battery mode. Once power was removed, the NAS immediately began its shutdown process. This test showed that the UPS integration with UGOS Pro allowed a fast and orderly shutdown sequence, preventing data corruption or incomplete writes. The reaction time was near instantaneous, and the system was powered down safely without user intervention. This mode may be best suited for environments where uptime during an outage is less critical than ensuring rapid data protection.

A third test focused on timed shutdown, with the UPS set to keep the NAS running for five minutes before initiating a safe power-off. Once mains power was disconnected, the NAS continued operating for the specified period, then shut down as configured. After power was restored, the UPS automatically triggered a restart of the NAS, returning it to full operation within a few minutes. This confirmed the UPS’s ability not only to handle outages but also to manage recovery without manual restart, which is beneficial for users who may not be present during a power failure.

During all tests, the device’s limitations became apparent. With a 120 W maximum output and battery capacity limited to 43.2 Wh, it cannot sustain extended operation. Its role is restricted to ensuring controlled shutdowns and short bridging periods rather than providing long-term backup. Furthermore, it supports only one NAS system via DC pass-through, so it cannot protect additional hardware such as routers or switches. Nevertheless, within its defined parameters, the UPS consistently delivered seamless transitions and executed software-triggered events reliably, confirming that its functionality matches its intended scope.

UGREEN US3000 UPS Review – Conclusion & Verdict

The UGREEN US3000 fills a specific role: protecting UGREEN NAS devices from sudden power loss. Its design avoids the bulk and inefficiency of conventional AC-based UPS units by delivering DC pass-through power with zero transfer time. In practice, it provides just enough runtime for the NAS to perform a controlled shutdown, while its software integration ensures automation of both power-off and restart processes. With lithium-ion cells, a compact aluminum chassis, and close alignment with UGOS Pro features, it is engineered as a dedicated accessory rather than a universal power backup solution.

As a result, its usefulness is limited to scenarios where a single UGREEN NAS is the priority. It does not offer multiple outputs or extended backup duration, making it unsuitable for wider network coverage or enterprise requirements. Instead, the US3000 should be viewed as a narrowly focused safeguard that addresses one problem reliably: preventing data corruption and incomplete writes during outages. For users within the UGREEN ecosystem, it is an effective solution, but for broader applications, its scope remains intentionally constrained.
